"So the question is, should Microsoft continue (presumably) forcing HTC to include the stylus-based keyboard if it means that people who don't know any better (which includes Boehret) think that's the only keyboard there is to use? The ability to toggle between various input methods isn't terribly discoverable"

Unhappily, what this question really asks is:

Should the rest of us dumb down to Boehret's level ?

The answer to that is clearly NO WAY!! These devices are both computers and phones - fight to the death to retain this. Idiots like Boehret are well suited to dumbphones.

The key is contained in the phrase "... isn't terribly discoverable". Changing this to "immediately and clearly pointed out" is simply a matter of better-designed manuals or help files.
